Abstract (en)

A pressure apparatus includes pressure sensing means (44a,46a), a reference device (60) and a temperature sensor (56) collocated within a common environment. The reference device and the temperature sensor are constructed to have temperature response times matched to the temperature response time of the pressure sensor to compensate for temperature gradients produced either by external heating or by pressure-volume heating.
